Parnassah Is Sent to Each Individual with Perfect Hashgachah

It says that Hashem gives each person his sustenance exactly when he needs it. Each person has a different trade and succeeds in gaining his sustenance when he needs it, with precise hashgachah pratis.

When Hashem split the Yam Suf, each Shevet had its own individual pathway, with the fruits and treats that its people needed; this is how Hashem still provides parnassah to each individual as well.

(Ksav Sofer, Vayechi)
